According to Adam Kilgore of the Washington Post, LaRoche was scratched from tonight’s lineup against the Diamondbacks due to soreness in his right oblique. The severity of the injury isn’t yet known, but as we’ve often seen, oblique strains can sideline players for weeks at a time.

After being limited to just 43 games last year due to surgery to repair a torn labrum in his left shoulder, LaRoche has been the most productive hitter in the Nationals’ lineup this season. The 32-year-old first baseman is batting .311/.392/.511 with four homers, 17 RBI and a .903 OPS across 102 plate appearances.
